Subject [jira] Created: (LUCENE-1180) Syns2Index fails
Date Fri, 15 Feb 2008 18:42:10 GMT
Syns2Index fails

                 Key: LUCENE-1180
             Project: Lucene - Java
          Issue Type: Bug
          Components: contrib/*
    Affects Versions: 2.3
            Reporter: Jeffrey Yang
            Priority: Minor

Running Syns2Index fails with a
java.lang.IllegalArgumentException: maxBufferedDocs must at least be 2 when enabled exception.
at org.apache.lucene.index.IndexWriter.setMaxBufferedDocs(
at org.apache.lucene.wordnet.Syns2Index.index(
at org.apache.lucene.wordnet.Syns2Index.main(

The code is here
		// blindly up these parameters for speed
		writer.setMergeFactor( writer.getMergeFactor() * 2);
		writer.setMaxBufferedDocs( writer.getMaxBufferedDocs() * 2);

It looks like getMaxBufferedDocs used to return 10, and now it returns -1, not sure when that
started happening.

My suggestion would be to just remove these three lines.  Since speed has already improved
vastly, there isn't a need to speed things up.
